Background: The present study aimed to evaluate the association between the cumulative dose of glucocorticoids (GCs) and case fatality in hospitalized patients who developed pneumonia while receiving glucocorticoid therapy.
Methods: This retrospective cohort study included 625 patients receiving long-term GC treatment who were hospitalized with pneumonia (322 male and 303 female). Data were obtained from the Dryad Digital Repository and were used to perform secondary analysis. Multivariable Cox proportional hazard regression model and restricted cubic splines (RCS) were used to evaluate the association between the cumulative dose of GCs and case fatality. Sensitivity analyses and subgroup analyses were performed.
Results: The 30-day and 90-day death rates were 22.9 and 26.2%, respectively. After adjusting for potential confounders, compared with those in the lowest quintile (≤ 1.5 g), the Cox proportional hazard regression model analysis showed that patients with different cumulative doses of GCs (1.5 to 2.95, 2.95 to 5, 5 to 11.5, and > 11.5 g) had lower risks for 30-day death, with respective hazard ratios of 0.86 (95% CI, 0.52 to 1.42), 0.81 (0.49 to 1.33), 0.29 (0.15 to 0.55), and 0.42 (0.22 to 0.79). The multivariable-adjusted RCS analysis suggested a statistically significant N-shaped association between the cumulative dose of GCs and 30-day death. A higher cumulative dose of GC tended to first lead to an increase in 30-day death within 1.8 g, then to a statistically significant decrease until around 8 g [HR for 1 g = 0.82 (0.69 to 0.97)], and again to an increase afterward. Similar results were found in the subgroup analyses and sensitivity analyses.
Conclusion: N-shaped association between the cumulative dose of GCs and case fatality was observed in patients receiving long-term GC treatment who were hospitalized with pneumonia. Our findings may help physicians manage these patients.

Importance: Isotretinoin is the only medical acne treatment capable of inducing acne remission; however, some patients experience acne relapse and require retrials of isotretinoin. There is a need to understand who is most at risk and how daily dose and cumulative dosage can influence outcomes.
Objective: To assess rates of acne relapse and isotretinoin retrial and to identify associated factors among patients with acne who received an isotretinoin treatment course.

Importance: Lung cancer in individuals who have never smoked (INS) is a growing global concern, with a rapidly increasing incidence and proportion among all lung cancer cases. Particularly in East Asia, opportunistic lung cancer screening (LCS) programs targeting INS have gained popularity. However, the sex-specific outcomes and drawbacks of screening INS remain unexplored, with data predominantly focused on women.

Importance: Recent studies have found an association between COVID-19 infection and deeper sedation in mechanically ventilated patients, raising concerns about the impact of the COVID-19 pandemic on pain, agitation, and delirium (PAD) management practices overall.
Objectives: This study aimed to assess differences in PAD management in patients without COVID-19 infection in pre- and peri-COVID-19 pandemic timeframes.
Design, Setting, And Participants: This was a single-center, retrospective, pre-/post-cohort analysis of mechanically ventilated adult patients without COVID-19 infection admitted to an ICU in Boston, MA.

Doxorubicin (DOX) is a powerful antineoplastic FDA-approved anthracycline-derived antibiotic and is considered as the most suitable intervention for solid tumors and hematological cancers therapy. However, its therapeutic application is highly limited due to acute and chronic renal, hematological and testicular toxicity. Oxidative stress, lipid peroxidation and apoptosis in germ cells as well as low sperm count, motility and disturbing steroidogenesis are the principal machineries of DOX-induced testicular toxicity.

Purpose: Treatment of pediatric cancers with doxorubicin is a common and predictable cause of cardiomyopathy. Early diagnosis of treatment-induced cardiotoxicity and intervention are major determinants for the prevention of advanced disease. The onset of cardiomyopathies is often accompanied by profound changes in lipid metabolism, including an enhanced uptake of short-chain fatty acids (SCFA).
